Tremendous! It has to help your health. I almost never have soft drinks (I devote myself to the sole vice of chocolate, mostly), but I gave up meat last year (though I do eat salmon still, so Toni says I didn't really give up meat), so I know the feeling of struggle and accomplishment. I temporarily gave up cheese this winter, but I have conclusively proved to myself that I can never be a vegan.

Meat can be fine for you, though meatless is a good way to go also. But there's no good side to sodas and fruit adds...so you win no matter what if you quit using them.
